Lap Steel Guitar:
The lap steel guitar is a type of steel guitar which is typically played with the instrument in a horizontal position on the performer’s lap or otherwise supported. The performer changes pitch by pressing a metal or glass bar against the strings as opposed to a traditional guitar where the performer's fingertips press the strings against frets. The bar placed against the strings is called a "steel" or "tone bar".
There are three types of lap steel guitars:
1. Acoustic lap steel guitar: The body resembles a traditional Spanish guitar. These were originally called "Hawaiian guitars", after the "slack-key" playing technique was popularized there in the late 1800s. These instruments are specifically designed to be played horizontally; i.e., the strings are higher off the fingerboard than a traditional guitar. Traditional guitars can be modified to play this way by using a "nut extender", a device to raise the strings.
2. National or Dobro-type guitars, which typically have reinforced square necks and feature a large aluminum cone, called a "resonator", to increase volume.
3. Electric lap steel guitars: These guitars are designed to be played horizontally and feature an electric pickup so they do not require any resonant chamber. Guitars in this category may differ markedly in external appearance and include instruments made from a rectangular solid block of wood. In addition to the lap-played model, a closely related version called a "console steel" guitar often featured more than one neck which made it too heavy to be played on the performer's lap. It is supported on legs (but does not include the pedals or knee levers of the pedal steel guitar). Electric lap steels typically have six, eight or up to ten strings....https://en.wikipedia.org/wiki/Lap_steel_guitar
Slide guitar is a particular technique for playing the guitar that is often used in blues-style music. The technique involves placing an object against the strings while playing to create glissando effects and deep vibratos that make the music emotionally expressive. It typically involves playing the guitar in the traditional position (flat against the body) with the use of a tubular "slide" fitted on one of the guitarist's fingers. The slide may be a metal or glass tube like the neck of a bottle. The term "bottleneck" was historically used to describe this type of playing. The strings are typically plucked while the slide is moved over the strings to change the pitch. The guitar may also be placed on the player's lap and played with a hand-held bar and is then referred to as "lap slide guitar" or "lap steel guitar".
Creating music with a slide of some type has been traced back to primitive stringed instruments in African culture and also to the origin of the steel guitar in Hawaii. Near the beginning of the twentieth century, blues musicians in the Mississippi Delta popularized the bottleneck slide guitar style, and the first recording of slide guitar was by Sylvester Weaver in 1923. Since the 1930s, performers including Robert Nighthawk, Earl Hooker, Elmore James and Muddy Waters popularized slide guitar in the electric blues genre and influenced later slide guitarists in the rock genre including the Rolling Stones, Duane Allman and Ry Cooder. Lap slide guitar pioneers include Oscar "Buddy" Woods, "Black Ace" Turner and Freddie Roulette.
Street Performance / Busking:
Street performance or busking is the act of performing in public places for gratuities. In many countries the rewards are generally in the form of money but other gratuities such as food, drink or gifts may be given. Street performance is practiced all over the world by men, women and children and dates back to antiquity. People engaging in this practice are called street performers or buskers.
Performances are anything that people find entertaining. Performers may do acrobatics, animal tricks, balloon twisting, caricatures, clowning, comedy, contortions, escapology, dance, singing, fire skills, flea circus, fortune-telling, juggling, magic, mime, living statue, musical performance, puppeteering, snake charming, storytelling or reciting poetry or prose, street art such as sketching and painting, street theatre, sword swallowing, and ventriloquism.
